DMM was founded in 1981 as Moorhouse Engineering in Bethesda, Wales. The company's original mission was to make the best possible climbing equipment at the best possible price. With just four employees, they started small, but they had big dreams.

In 1986, DMM moved to more suitable premises in Llanberis, Wales. This was a major turning point for the company, and it allowed them to expand their operations and reach a wider audience. Over the next few decades, DMM continued to grow and innovate. They developed new products, expanded into new markets, and became a leading manufacturer of climbing equipment. Today, DMM employs over 200 people and is an important employer in the local area.

DMM's success is a testament to the hard work and dedication of its employees. They are passionate about climbing and committed to making the best possible products. DMM is a true industry leader, and they are excited to continue their journey for many years to come.
